PURPOSE: A rubber composition for an automotive engine mount is provided to enhance thermal resistance and to maintain a low dynamic ratio by enhancing a dynamic characteristic. CONSTITUTION: A rubber composition for automotive engine mount comprises 0.4-1.5 parts by weight of sulfur, 0.5-3.5 parts of N-cyclohexyl-2-benzothiazyl-sulfenamide, 0.5-3.5 parts of tetramethylthiuram disulfide, 2-8 parts of a peroxide cross-linker, 15-30 parts of SRF(semi-reinforcing furnace) carbon black, 10-20 parts of FEF(fast extrusion furnace) carbon black, and 4-6 parts of paraffinic oil based on an EPDM mixture which blends EPDM 1 which does not include oil and EPDM 2 which includes oil at the weight ratio of 1:3. As additives, 2-7 parts by weight of activated zinc, 1-3 parts of stearic acid, 1-2 parts of SUN 682(Sunprax) and 2-4 parts of 13 C (N-phenyl-N'-isopropyl-p-phenylenediamine) are included.
